JOSEIPH GRAUER, OF NEW YORK, N.. Y.

PIPE-CUTTER.

Application filed February 6, 1915.

To all whom it may concern:

Be it known that I, JosErH GRAnnR, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented a certain new and useful Improvement in Pipe-Cutters, of which the following is a specification, reference being bad to the accompanying drawings, which form a part of the same.

The object of my invention is to provide a tool adapted to conveniently cut off the ends of pipe which protrude beyond the point convenient for the most acceptable construction and at the same time arranging such cutter so that it may readily be manipulated to cut off the ends of pipe, to which the present cutters are not readily accessible, such as projections inside of junction boxes and similar constructions. V

In the drawings, Figure 1 is a side elevation of a pipe cutter embodying my invention, partly shown in section; Fig. 2 is-a cross section taken at the line AA of Fig. 1; Fig. 3 is a sectional view taken at the line BB of Fig. 1, looking in the direction of the unlettered arrow; and Fig. 4 is a plan view of my pipe cutter.

Referring now in detail to the drawings, 1 represents a housing having integrally connected therewith the bushings 2'-2 and --2" in which are rocked the levers 3, 3, respectively, the same being loosely mounted on pins 4, 41 in said bushings. The said rocking levers 3, 3 are manipulated by means of thumb screws 5, 5 which extend through one of the ends of each of said levers, being screw threaded therethrough. The ends of the said screws play against the housing 1 as the same are manipulated. The end of the rocking lever 3 opposite to the end containing the thumb screw is inserted in a pipe guide 6, which slides in the guide-ways 7, made integral with the housing 1. This pipe guide 6 is provided with teeth or ridges 8 which are preferably arranged at an 0btuse angle to the pipe which they are adapted to grip. The rocking lever 3 opposite to its screw tension end is fitted into the re cess 9 of the cutter 10. This cutter is adapted to slide in the stationary pipe holder 11, which pipe holder is provided with ridges 12 which are preferably made straight so that when the pipe is in position to be cut it will be held at three circumferential points, namely, at one point by the straight Specification of Letters Patent.

ridge 12 and at two points by the angular ridge 8.

In order to manipulate the pipe cutter when in position I have provided handle bars 13 which are adapted to be screwed into the housing 1 at the holes 14. I have also provided holes 15 in the housing which are larger than the holes 14 so that the bar 13 may be inserted therethrough for the purpose of manipulation of the pipe cutter when it is found inconvenient to screw the said bar into the housing.

In the housing 1, on each side thereof, I have provided an opening 16 opposite the ridges 8 and 12 and the blade of the cutter 10 for the purpose of inspecting the position of the pipe with reference to the pipe cutter before the same is manipulated. These openings 16 also permit chips-to be discharged from the tool, while the same is in operation.

The operation of pipe cutter is as follows: The tool is placed over a projecting piece of pipe and the thumb screw 5 is screwed down against the housing 1, which operation has the effect of raising the tension end of the rocking lever 3 and gripping the pipe to be out at the opposite end of said lever by its action upon the pipe holder 6. The thumb screw 5' may then be screwed against the housing 1, which operation brings the cutter 10 into operative contact with the pipe 17 to be cut. Assuming that the handle bars 13 are in place the tool may be readily turned on the pipe 17, the blade of the cutter 10 effecting a circumferential incision into the pipe at the point where it is desired to cut the same. As the cutter becomes free by reason of the incision made in the pipe, the thumb screws or one of them may be screwed farther down, so as to give a new cutting area for the blade. This operation is continued until the pipe end is completely severed. Of course it will be understood that the cutting edge of the blade is disposed at one side of and slightly above the ridges 12 of the pipe holder 11.

In the above description and the accompanying drawings I have shown the preferable embodiment of my invention but I do not wish to be confined to the disclosure therein contained but What I desire to cover by Letters Patent is set forth in the appended claims.

1. In a pipe. cutter, a housing, levers adapted to rock on said housing, one end of each of said levers having means for rocking said levers, an adjustable cutter at the other end of one of said rocking levers, and an adJuStable pipe holder at the other endof the other of said rocking levers, said plpe holder being. angular in form, and a sec-" ond pipe holder being straight in form and disposed opposite to the angularpipeholder, handle bars adapted to be connected With said housing, alternative or supplemental holes in said housing for the purpose of'in'anipulating the said tool upon the insertion of'a bar"therethrough, and sight cut-aways in said housing.
